I’ve talked to some gankers, including Aiko, and the sentiment is that it’s not a matter of difficulty or being unable to adapt, but that ganking is simply becoming out of reach now because there just aren’t enough players to do it.
They can no longer make money from it, and you can say “well, they shouldn’t.”
They can’t solo-gank even the weakest untanked barges now, and you can say “well, they shouldn’t.”
But now it’s impossible to gank a target of moderate difficulty like a Mackinaw in a 0.6 system without using nearly 10 people, and you can’t say “get more alts” because that shouldn’t be a solution to anything in EVE. For all other activities in EVE, getting more accounts results in efficiency scaling, but for ganking, it has become a minimum requirement.
Also, all of this is before we even get to other considerations, like AG presence. For all the complaints about how gankers are “protected by CONCORD,” it applies much more to AGs because they can neutralize a gank just by using a single disposable NPC-corp alt in a 400,000 ISK Griffin with no modules except an ECM burst. There’s no combat-based counter-play to that, just like there isn’t any counter-play to, say, a one-shot Tornado gank.
CCP has catastrophically failed to develop good gameplay here, has distilled this entire complex system of player interaction to one-button insta-shitting on each other, and being forced to get more characters.
And the fundamental reality going forward is that ganking might significantly decrease in volume because there just aren’t enough criminally-minded players left in the game to be able to deal with the numbers game, regardless of how much they’re personally willing to adapt to changes. Being unable to use half a dozen accounts at the same time isn’t lack of adaptation, but a genuine real-life physical barrier for many people.
